2013-2-1  1. Introduction. The term rare earth elements (REEs) refers to the fifteen metallic elements of the lanthanide series, coupled with the chemically similar ytrrium, and occasionally scandium (Gupta and Krishnamurthy, 1992).These elements are typically split into two sub-groups, the cerium sub-group of “Light” rare earth elements (LREEs) which includes La to Eu and the yttrium sub-group of ...

The rare earth elements are, contrary to the name, relatively abundant in the Earth's crust. Cerium which is the most abundant rare earth element, as shown in FIG. 1, is more plentiful than copper, lead, etc. [1]. The estimated average concentration of the rare earth elements is around 150 ppm shown in Table 2.1.

Separation of Radioactive Elements from Rare Earth

Rare earth elements (REE), originally found in various low-grade deposits in the form of different minerals, are associated with gangues that have similar physicochemical properties. However, the production of REE is attractive due to their numerous applications in advanced materials and new technologies. The presence of the radioactive elements, thorium and uranium, in the REE deposits, is
